This invention relates to improvements in car construction,

One object of the invention is to provide a combined locking and centerpin arrangement for railway cars of rugged design, in-

cluding a connecting element comprising a plural-ity of sections and aspacing member, certain of the sections having shouldered engagementwith the car holsters to prevent separation thereof, the sections whencollapsed by removing the spacing member being of such dimensions incross section that they will pass freely through the center pinreceiving openings, the shouldered engage- 1'5 ment between the sectionsand the cooperating bolster being provided by a tapered seat on thebolster and cooperating expanded tapered head portions on said sections.

Another object of the invention is to provide means for connecting thebody and truck holsters of railway cars including a sectionalcenter'l'pin comprising outer sections and a spreading member, saidouter sections being interlocked with the cooperating bolster by atapered head of greater size than the main sha-nk portion of the pin andcooperating with a vtapered Vseat on the bolster, portions of'said 'headVbeing Aformed on each of the outer 'sections and the sections beingheld apart by the spreading "member to lool; the head to the-bolster,'Said outer ysections being collapsible "when the spreading 'member' iswithdrawn from betweenvthe same to reduce the cross sectional a'rea'oi"said tapered head to permit insertion of the parts through the pinreceiving openings of the holsters.

further 'object of the invention is toV provide acenter pinconstructionffor connecting the body and truck holsters ora railway carprovided 'with aligned center pin receiving openings, wherein the pinisheaded at oppositeende to interlock the'eanie' with both bol,- stere'endis collapsible to reduce the sizeof each of the heads "to permitinsertion of the parte through the piny receiving openings, byent-"eringthe'same either through the body or truck bolster opening, oneof saidheadjinembers 'being tapered and cooperating with a tapered seat'on the jeorree'ponding bolster. do' A niore 'specific cbjectof `theinvention is to provide a combined locking andcenter pin l arrangementfor body and truck holsters of railway cars, including a pin propercomposed o'f a pair of counterpart outer sections and a spreading memberinterposed therebei tween, each of the outer sections havingenlargements at the opposite ends thereofforming portions of headmembers by which the sections are anchored to both holsters, one of saidheads being tapered, increasing in size toward the extremity of the pin,and the cooperating bolster being formed with a ltapered seat for saidhead, whereby, when the spreading member is withdrawn from between saidsections, the latterare collapsible to effect reduction in size of thepin, the tapered head member being of such cross sectional area that thesections pass through the pin receiving opening 'of the holster when theparts are collapsed.

Other and further objects of the invention will more clearly appear fromthe description and claims hereinafter following.

Inwthe drawing forming a part of this specification, Figure 1 is a topplan view of 75 the body and truck holsters of a railwayr car,illustrating my improvements in connection therewith. Figure 2 is avertical sectional view, corresponding substantially to the line 2-2 ofFigure 1. Figure 3 is a so horizontal transverse sectional view, partlybroken away, corresponding substantially to the line 3 3 of Figure 2.And Figure 4 isA a detailedelevational view of a spreading or Vfillermember employed in connection with y85 my improved combined locking andcenter pin construction.

In said drawing, 10 indicates generally a portion of the body bolster ofa railway car and 11 the cooperating truck bolster. The 90 body bolsteris provided with the usual top and bottom webs and a cylindrical sleevesectionf12 connecting the same. At the bottom, the bolster 10 isprovidedwith a downward projection 13 having a substantially spherical 95bearing surface cooperating with a spherical bearing seat 14 formed on aybearing block 15 seated in a pocket 16 on the'truck bolster.

The truckbolster 11 is also provided with 100 the usual top and bottomwebs connected by a central sleeve-like section 17. The body and truckholsters are provided with center pin receiving openings and an alignedopening in the Ybearing plate 15, the opening in the bearing` platebeing surrounded by an upstanding' annular flange 18 which engageswithin a. seat 19 formed on the bottom of the body bolster.

In carrying out my invention, I provide the truck bolster with a centerpin receiving opening 20 which is of smaller diameter than the lnainportion of the sleeve-like section 17, whereby a pocket 21 is providedto accommodate the head member at the lower end of the center pin. Anannular shoulder 22 is thus provided in the pocket surrounding thecenter pin receiving opening 20. The bearing plate 15 is provided with acenter pin receiving opening 23 of the same diameter as cned, as clearlyshown in Figure 2, and said lower end portion of the sleeve is providedV^V`-with a center pin opening 24 of substantially the same diameter asthe openings 2O and 23. Immediately above the opening 24, the innerfaces of the walls of the sleeve 12 are flared upwardly to provide atapered seat 25 which fifcooperates with thecenter .pin membeiyashereinafter more clearly pointed out. Above the tapered seat 25, theopening in the bolster may be made of. larger diameter than the AAupperportion of the seat, or said opening may be made of thesame diameter asthe upper portion of the seat.

My improved combinedv center and locking pin proper comprises a pair ofcounterpart` outer sections A-A and a'central section B w'which forms afiller or spreading member.

Each of the sections A has a central shank portion 26 and a laterallyoutwardly projecting flange 27 at the bottom end thereof. At the upperend, each section is enlarged` as indicated at 28. The enlargement 28 ofeach section fits the corresponding side of the Y.

tapered seat 25 of the bolster 10, as clearly illustrated in Figures 1and 2.

VOn theA inner sides, the sections A present flat vertical faces. which,when brought into abutment b v displacing one section laterallyinwardly, reduce the crosssectionalarea of the head formedby thek flangeportions 27 at the bottom ends of the sections A and the cross sectionalarea of the retaining means formed by the enlargements 28 atY the upperend of said sections, so that the displaced sec-.

tion Amay be withdrawn, the .head portion at the bottomend of saidsection and the retaining `means at the` top end thereof being ofsuch asize as to pass freely through the pin receiving openings 20, 23 and24.The remaining section may then be displaced laterallyto register theflange and enlargement thereof with the pin receiving openings, and isthen withdrawn in a similar manner. As will be clear upon reference toFigures 1 and 3, the opposite side portions of the head formed by theflanges 27, as well as the opposite side portions of the retaining meansformed by the enlargement28, arefcut away so as to'provide properclearance to permit the flanges and enlargements of the sections A topass through the' pin receiving openings of the holsters.-

The filler or spreading member B is in the form of a'relatively thickplate having upwardly diverging side edge portions 29 adjacent theupperY end thereof, which are adapted to seat on the opposite side wallsof the tapered seat 25 to limit downward move ment of said member B. Themember B is of such a thickness that it will hold thev sections Aseparated to such an extent that the flanges v27 will overhang theannular shoulder 22 and that the tapered enlargements 28 will be seatedon the walls of the tapered seat In order to facilitate the removal ofthe member B, the same is preferably provided with an upstandinglug-like member 30 at the upper end thereof, provided with an opening 31adapted to cooperate with the hook portion of a tool by which the memberB may be lifted upwardly.

The outer sections A are also preferably provided with similar lugs32-32 vhaving openings 33-38 within which a tool may be engaged to liftthe same out of the opening in the. bolster 10.

In assembling my improved combined locking and center pin with the bodyand truck bolsters of a railway car, one of the. sections A is first.inserted through the center pin openings of the bolsters and displacedlaterally to overlap the flange 27 with the shoulder of the truckbolster and seat the head section 28 on the tapered seat portion 25. Theother section A is then inserted, the inner side thereof being at thistime in contact with the inner side ofthe section A first applied, so asto reducethe cross sectional area of the head member and the taperedvretaining means, as hereinbefore pointed out, so that the flange andenlargement of the last named section will pass through the pinreceiving openings of the holsters; VAs will be-evident,the sectionsA-may be applied by inserti-ng the same in succession through `the topof the body bolster and passing the flanges at-the lower ends thereofthrough said pin receiving openings until the same are dislil 0 posedbelow the annular shoulder 22 of the y truck bolster, or by insertingthe sections successively upwardly through theV opening of the truckbolsterl and passingV the enlargements l28 through the pinrecelvingopenings until said enlargements register with the seat 25.the'prts have-been thus far lthrough the opening in the body bolster.V

The-sections will thus be held apart with the flanges 27 in overlappingrelation with the annular shoulder 22 and Ythe enlargements 28 seated onthe opposite side wall portions :of the seat 25, thereby anchoring thepin to both bolsters and preventing separation of the latter.

When it is desired to separate the bolsters, the pin is readily removedby withdrawing themember B from between the sections A and thencollapsing the sections by displacingr one of the same laterallyinwardly and bringing them into contact, whereupon the displaced sectionmay be irst withdrawn, the

i other section being then displaced laterally inwardly to register theenlargement and Harige thereof with the pin receiving openings,whereupon said last named section may be withdrawn. As will be evident,the sections may be withdrawn either through the bers on both bolsters.It is also pointed out that the member B may be inserted through theopening in the truck bolster, instead of through the opening in the bodybolster. as shown, it being merely necessary to form the member of thesame width from top to bottom, eliminating the inclined edge portions 29and providing any well known retaining means for limiting the downwardmovement of said member.

While I have herein shown and described what I now consider thepreferred manner 0I carrying out my invention, the same is merelyillustrative and I contemplate all changes and modifications which comewithin the scope of the claims appended hereto.

I claim: l. In car construction, the combination with body and truckbolsters having aligned y center pin receiving openings; of a pin hav-"in a reverse direction, said pin comprising a plurality ot' -sectionsincluding a spreading member which when removed permits collapse 'o thepin to eiiect reduction in size oi' said tapered head to allow passagethereof through the pin receiving openings.
